HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 821, 959, 577 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 821, 959, 577 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 821, 959, 577 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 821, 959, 577 is 1.

HCF(821, 959, 577) = 1

HCF of 821, 959, 577 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 821, 959, 577 is 1.

Highest Common Factor of 821,959,577 using Euclid's algorithm

Highest Common Factor of 821,959,577 is 1

Step 1: Since 959 > 821, we apply the division lemma to 959 and 821, to get

959 = 821 x 1 + 138

Step 2: Since the reminder 821 ≠ 0, we apply division lemma to 138 and 821, to get

821 = 138 x 5 + 131

Step 3: We consider the new divisor 138 and the new remainder 131, and apply the division lemma to get

138 = 131 x 1 + 7

We consider the new divisor 131 and the new remainder 7,and apply the division lemma to get

131 = 7 x 18 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 821 and 959 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(131,7) = HCF(138,131) = HCF(821,138) = HCF(959,821) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 577 > 1, we apply the division lemma to 577 and 1, to get

577 = 1 x 577 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 577 is 1

Notice that 1 = HCF(577,1) .
